A novel LED backlight device is introduced in this paper, which is mainly used for transparent or translucent glass bottle detection relevant to machine vision. A special controlling and drive circuit is adopted in this LED backlight device to realize independent control of each color and rapid and convenient change of many colors and luminance. Because the area of LED backlight can be changed at...
The distributing map of surface reflectivity of Shanghai city and its adjacent areas is generated by MODIS remote sensing image. According to the surface spectrum features of this area and the changing characters of surface reflectivity caused by MODIS pixels, we explain the distributing map of surface reflectivity as follows. In the fifth wave band of MODIS, the distributing map of surface reflectivity...
Sino-Singapore Tianjin Eco-city is a strategic cooperation project between China and Singapore to build an eco-culture and improve the people's living environment. In this paper, to ensure this target, some implementation stategies were put froward which including building a sustainable resource using system with intensive development mode, a low-carbon eco-industrial system cycle, a safe and healthy...
The air-side flow and heat transfer characteristics of steel tube brazing snake-like fins for direct air-cooled condenser is numerical simulated with the help of computational fluid dynamics (CFD) software. The affect between the comprehensive heat transfer performance indicators and the fin height and wind speeds is discussed. The correlation of flow resistance and heat transfer coefficient with...
After analyzing the feature of industrialized breeding and the wireless sensor network, the paper proposes a solution to automatic water monitoring system of industrialized breeding based on Zigbee protocol. The system design based on MG2455 MCU, a product of Radio Pulse Co., is emphasized in the paper, and the real-time monitoring and management of remote water quality data is implemented in the...
This paper introduces the practical experience of putting up a management platform of exchange and feedback of teaching information for students with modern network and information technology. In order to put up this platform, it discusses the four aspects in detail: building the system for student information clerk; holding student symposiums regularly; establishing a personal learning management...
A Hybrid Particle Swarm Optimization (HPSO) with parameter selection approaches is proposed to solve Flow Shop Scheduling Problem (FSSP) with the objective of minimizing makespan. The HPSO integrates the basic structure of a Particle Swarm Optimization (PSO) together with features borrowed from the fields of Tabu Search (TS), Simulated Annealing (SA). The algorithm works from a population of candidate...
Internet is a kind of special media whose birth has brought great influences on democratic politics, in which there are both positive and negative influences. As the Internet is more and more popular, the population of net-citizens is increasing, so that the Internet media is used more and more widely in China, and plays an active role and also brings a negative role. Therefore, the Internet media...
In view of the paperless teaching and the test situation of programming curriculums, this paper employed the analytic hierarchy process (AHP) to construct achievement evaluation indicator system and the examination paper evaluation indicator system for programming curriculums group. This evaluation indicator system made full use of the wealth of information of the process of paperless teaching and...
